734240 ÷ 90 
We want to divide 734240 by 90.

Advancing to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 90

Advancing to step 2:
When dividing 73 by 90, we get 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 90

On to step 3:
90 goes into 734 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 720 from 734 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 90

On to step 4:
When dividing 142 by 90, we get 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 90 away from 142, we end up with 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 90

Advancing to step 5:
90 goes into 524 5 times with a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 815.0
Subtract 450 from 524 to get 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 90

On to step 6:
90 goes into 740 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8158.0
Deduct 720 from 740 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 90, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 8158.2
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 8158.22
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 8158.22, with a leftover of 0.02.
